IMPRovriMnNT IN ovens.

` The Schedule referred to 1n these Letters Patent and making-part of the same.

To all whom 'it may concern:

Be itknown that I, GEORGE RODNEY MOORE, of Philadelphia, in the county of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Oven-Doors and Gasings'; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The object of my invention is to prevent, in the most effectual manner, heat radiation outward, from portable and other ovens, through the doors and casings. Also, to provide a cheap and durable ovenpyrometer.

Figure 1 is a plan view of the inside of an ovendoor, and shows the 'arrangement of thepyrometrcal levers. l

Figure 2 is a'plan view of vthe outside of the door, and shows, within the anges a. a. a a, a panel of wood, b. Under'this panel or casing of wood there is a quantity of paper over the iron body and frame-work ofthe door.

Figure 3 shows a cross-'section of the same, b showing the wood, c, the papel', and d, the iron.

Figure 4 shows another kind Of-ange, e, more douvenieut for attachingcasings to. tin o1" 'sheet-iron ovens. It is thus seen that the frame-'works of the oven are made with suitable anges for holding whatever nolnradiating materials it may bedeemed best-to use for casings; in this instance, several thicknesses of paper,

overlaid with a panel of wood. Also, from tig. 4, that suitable anges or rims, e, may be made separate for holding casings upon ovens that are not cast.

The operation of the -pyrometrical levers 1s obvious.

A vibrates upona stationary pivot, and, having an l Having thus fully described my invention,

What I claim therein as new, and desire to secure by 1. The construction of oven-doors and sides, with casings of paper and wood, or-their equivalents, substantially'as and for the purposeherein set forth.

2. The pyrometrical levers A B C, arranged as he1e.
